Rowlands Marine in North Wales have installed the MERMAID M16 aircon unit. It is 16000BTU which will give plenty of reserve for use in the Caribbean. With the large saloon windows the thermal gain will be high so it will be interesting to see how effective it proves to be. After much debate it was decided to position it under the chart table. This involved significant fabrication but has saved vital space. It runs on AC so can be used by the generator but is more likely to be used in marinas. The ducting delivers cooled air to both the Saloon and also the aft cabin. The thermostat and controls are in the aft cabin.
